Thank you for your question, it´s Christian/ Tanja the CEO and Founder of Equine 74 Gastric answering your question! Please introduce your vet Equine 74 Gastric, please tell him that we have done a scientific pre-reviewed study (Journal of Equine Veterinary Science 34 (2014) 391–397 Original Research) and may he can have a look at it. A lot of European Vets recommend Equine 74 Gastric as a daily based supplement, after using, for example, Gastrogard or some other products with Omeprazol. These products are in Europe Medicine products and the Vets try to treat a horse only for a very short time, mainly 14 - 21 days. As soon as you reduce the Medicine the vets recommend Equine 74 Gastric.
